asbestos

Leon Hupperichs

Asbestos found in rock near a proposed iron mine is raising questions about mine safety, especially for workers.  

A Northland College professor says he found a mineral called grunerite sandwiched between layers of iron ore. 

Geoscience Professor Tom Fitz says grunerite does not always take the form of the long slender fibers that characterize asbestos.  But he says in this case, it does.
